47. The main two components of CPU are ___ .
- Option : A
- Explanation : CPU is the abbreviation for central processing
unit. The CPU is the brains of the computer
where most calculations take place. In terms
of computing power, the CPU is the most
important element of a computer system.
Central processing units have two primary
components;
(i) The arithmetic logic unit (ALU) is the CPU component that performs the processor's actual computations. Its circuitry calculates the addition, subtraction, multiplication and division equations in the instructions the control unit passes to it. The ALU also performs logical operations that are essential to the control structures that regulate software flow.
(ii) The control unit (CU) regulates the processor's operation and the arithmetic logic unit that actually crunches numbers and compares values. However, these two clusters of transistors still rely on memory resources in the computer the CPU powers in order to function.
48. The methods of learning in Higher Education in India in the past consisted of
- Option : B
- Explanation : Ancient Indian Education was for a long time imparted through the oral lesson, without the medium of a book. Oral recitation was the basic medium of imparting knowledge and was practiced through various methods like introspection (listening, contemplation and concentrated contemplation), storytelling, memorization, critical analysis, practical study and seminars.
- Option : C
- Explanation : Research Promotion Scheme (RPS) Promotes Research in identified thrust areas of in Technical Education. RPS is aimed to create research ambience in the institutes by promoting research in engineering sciences and innovations in established and newer technologies; and to generate Master's and Doctoral degree candidates to augment the quality of faculty and research. The limit of funding is Rs 25 Lakh for project duration of3 years.
50. Blue - baby syndrome can happen due to excess of which component in water?
- Option : C
- Explanation : Blue Baby Syndrome , or methemogiobinemia,
begins when large amounts of nitrates in water
are ingested by an infant and converted to
nitrite by the digestive system. The nitrite
then reacts with oxyhemoglobin (the oxygen-
carrying blood protein) to form metheglobin,
which cannot carry oxygen.
If a large enough amount of metheglobin is formed in the blood, body tissues may be deprived of oxygen, causing the infant to develop a blue coloration of their mucous membranes and possibly digestive and respiratory problems. This condition is also known as methemoglobinemia. The majority of cases have occurred when nitrate levels have been over 100 mg/litre.
